TwitchCon cosplay contest finalists.

TwitchCon’s craziest cosplay creations show how dedicated gamers can be

Cosplay, or costume play where people dress up as their favorite game characters, isn’t quite a sport yet. But it’s certainly a form of art, as shown by the entrants in the cosplay contest for the TwitchCon 2018 streamers event in San Jose, California. The finalists put hundreds of hours of work into their creations.

Casey Renee of Casey Renee Cosplay won the categories for the best needlework and best overall cosplay at the event, and she spent more than 550 hours patterning, sewing, and adding details to the Amethyst by the artist Sakizou. For that dedication, she walked away with the $15,000 grand prize.
